The point on a line through the ends of the meter stick is the electric field equal to zero is 4.7 m from the 0 cm mark.

An electric field is the physical field that surrounds the electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them. It also refers to physical field for a system of charged particles. Electric fields originate from the electric charges and time-varying electric currents. Electric fields and the magnetic fields are both manifestations of the electromagnetic field, one of the four fundamental interactions (also called forces) of nature.

Electric fields are important in many areas of the physics, and are exploited in electrical technology. In atomic physics and chemistry, for the instance, the electric field is the attractive force holding the atomic nucleus and electrons together in atoms. It is also force responsible for chemical bonding between atoms that result in molecules.

The electric field is defined as a vector field that associates to each point in the space the (electrostatic or Coulomb) force per unit of charge exerted on an infinitesimal positive test charge at rest at that point. The derived SI unit for electric field is the volt per meter (V/m), which is equal to the newton per coulomb (N/C)

Before telemedicine to provide high-quality medical treatments remotely, a dependable broadband telecommunications network must be established, and licensing obstacles in the states must be removed.

Telemedicine is the delivery and support of healthcare services over long distances using electronic information and communication technology. Distance is denoted by the Greek term "tele," and healing is denoted by the Latin word "mederi." Telemedicine can improve patient access to healthcare services, cut healthcare expenses, increase efficiency and income, and ultimately result in patients who are happier and healthier and stay with your organization. Store-and-forward, remote monitoring, and real-time interactive services are the three primary categories of telemedicine. Each of these plays a positive role in overall healthcare and, when used appropriately, can provide real advantages for both patients and healthcare professionals. Enhancing overall patient outcomes ought to be telemedicine's main objective.

A ball is thrown vertically downward with an initial speed of 15.8 m/s from a building whose height is 122 m. It takes the ball 3.63 s to strike the ground.

Because the object is moving downhill vertically, the motion has a negative acceleration value as well as a negative velocity value.

A quadratic function with concavity downwards can be used to represent both this kind of motion and the motion of the object thrown above.

h = h0 - v0t - [tex]\frac{gt^2}{2}[/tex]

so putting all the values, we have,

0 = 122 - 15.8t - 4.9 [tex]t^{2}[/tex]

then we know the formula,

t= [tex]\frac{-b±\sqrt{b^2-4ac}}{2a}[/tex] here a=-4.9 b= -15.8 c =122

The four states of matter that can be encountered in daily life are solid, liquid, gas, and plasma. It is believed that many other states can only be found in extremely cold or dense matter, including the Bose-Einstein condensate and neutron degenerate matter. Quark-gluon plasmas are among the other conceivable states that are currently thought to be hypothetical.

The states that can exist inside the gadget are gaseous, liquid, or solid. A solid can be identified by its hard form, strong atomic bonds, and high viscosity. Insofar as they have a three-dimensional periodic atomic structure, most solids are crystalline; nevertheless, some solids (like glass) lack this periodic arrangement and are non-crystalline or amorphous instead.

According to the question,

The solid is densely packed with particles. The forces between the particles are so strong that they are only able to vibrate and not move freely. The solid as a result has a steady, distinct shape as well as a specific volume.

A liquid is a nearly incompressible fluid with a constant volume regardless of the pressure that adapts to the shape of its container. If both temperature and pressure are constant, volume is defined. When a solid is heated over its melting point, it turns liquid because the pressure exceeds the material's triple point.
